Inventor: HIRAMATSU KIYOSHI
IPC: H04N5/445
Filed: 1980-06-02
Abstract: PURPOSE: To enable super-display economically with a small circuit scale, by adding and weighting a prescribed signal to an address signal which reads out a pattern memory in synchronizing with the scanning of a cathode ray tube.  
     CONSTITUTION: In a variable super-display signal generating circuit 54, an address signal toward vertical direction generated with a main clock generating circuit 16 and a prescribed signal generated with an addition value set circuit 56 are fed to an addition circuit 55. As a result, an address signal produced from the circuit 54 drives a super-display signal generating circuit 57 as a signal weighted by a value set to the circuit 56 to the address signal produced from the circuit 16. A super- display signal produced from the circuit 57 controls a mixing circuit via a switch circuit 58 with a switch selecting information from a selection indication circuit 59. With this constitution, since the screen control means for super-displays of many kinds is not necessary, allowing to make the circuit scale small.

Title: Bellows permitting torsional deformation
Inventor: YAMAMOTO KEN
IPC: F16J3/04
Filed: 1979-06-11
Abstract: PURPOSE: To obtain a bellows permitting torsional deformation by an arrangement wherein the bellows is structured by coupling a plurality of bellows segments which can be bent in the specified direction by an external force.  
     CONSTITUTION: Each bellows segment used in this bellows is such structured, as shown in the drawing, that is produces bending deformation in the specified direction when exerting an external force thereupon. On thus structured bellows segment, another segment of the same type is superimposed with an angular shift θ to each other in their bending directions and joined thereto. This process is repeated many times to join the segments with one another in turn so that a bellows B is obtained. Thus obtained bellows B has such an ideal form that a normal bellows shows when it produces uniform distribution of torsional deformation upon the exertion of a torsional force thereupon, whereby the bellows B becomes highly durable against torsion.

Title: Method of evaluating dispersion of magnetic paint
Inventor: IGARI HIDETAKA
IPC: G01N27/72
Filed: 1989-03-24
Abstract: PURPOSE:To obtain magnetic paint having excellent characteristics by facilitating the determination of the optimum dispersion final point by applying the magnetic paint to a carrier to dry the same before measuring the coercive forces of the magnetic paint film at different temps. CONSTITUTION:Magnetic paint for a magnetic recording medium prepared by dispersing a magnetic powder in a dispersing medium is applied to a carrier and, after drying, the coercive forces of the paint film composed of the magnetic paint are measured at different temps. If needle particles keep the axial ratio at the time of compounding when the difference between coercive forces is calculated, there is no difference between the coercive forces measured at different temps. even when particles are flocculated or dispersed individually. However, when needle particles are damaged and a powder having a small axial ratio becomes a state contained in the magnetic paint, the difference between the coercive forces becomes large suddenly and the paint film using the magnetic paint of this kind is also large in transfer. By this method, the damage of the needle particles in dispersion treatment and the degree of transfer due to the damage of said particles can be foreknown and the use of the magnetic paint becoming easy to transfer by excessive dispersion can be avoided.

Title: Manufacture of magnetic material
Inventor: KANO HIROSHI
IPC: H01F41/18
Filed: 1985-04-10
Abstract: PURPOSE:To enable to control a coercive force by feeding hydrocarbon gas into a sputtering atmosphere when accumulating a magnetic material on a base by a sputtering method. CONSTITUTION:The coercive force of a magnetic material can be controlled by feeding hydrocarbon gas into a sputtering atmosphere. The reason is not always clear, but it is considered by the mixture of carbon in a thin magnetic film due to the decomposition of the gas in the atmosphere. As methane gas concentration in the atmosphere increases, the coercive force of the film increases. Since the hydrocarbon having large molecular weight is decomposed in the atmosphere to produce methane, further carbon and hydrogen, it is considered that the operation is substantially the same.
